HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 228, 133, 864 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 228, 133, 864 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 228, 133, 864 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 228, 133, 864 is 1.
HCF(228, 133, 864) = 1
HCF of 228, 133, 864 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 228, 133, 864 is 1.
Highest Common Factor of 228,133,864 is 1
Step 1: Since 228 > 133, we apply the division lemma to 228 and 133, to get
228 = 133 x 1 + 95
Step 2: Since the reminder 133 ≠ 0, we apply division lemma to 95 and 133, to get
133 = 95 x 1 + 38
Step 3: We consider the new divisor 95 and the new remainder 38, and apply the division lemma to get
95 = 38 x 2 + 19
We consider the new divisor 38 and the new remainder 19, and apply the division lemma to get
38 = 19 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 19, the HCF of 228 and 133 is 19
Notice that 19 = HCF(38,19) = HCF(95,38) = HCF(133,95) = HCF(228,133) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 864 > 19, we apply the division lemma to 864 and 19, to get
864 = 19 x 45 + 9
Step 2: Since the reminder 19 ≠ 0, we apply division lemma to 9 and 19, to get
19 = 9 x 2 + 1
Step 3: We consider the new divisor 9 and the new remainder 1, and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 19 and 864 is 1
Notice that 1 = HCF(9,1) = HCF(19,9) = HCF(864,19) .
